The present novel creation relates to various embodiments of safety devices for interior swing doors, The door may be a single swinging door or one of a pair of co-mounted doors. As mentioned above, a swinging "swing door" is a door that opens about a set of hinges that are mounted to the inner frame portion of the door frame. As used herein, the term "co-mounted" means that two conventional doors are mounted along respective common side hinges to the door frame or door jamb of a residential, commercial or other building such that each door is hinged along a common side to which the frame is hinged. The sides are opposite to open and close. As used herein, the term "connected" means that opposing parts of the door handle assembly mounted to each commonly installed door (i.e., the portion facing the door handle assembly) are connected or coupled to each other and are mutually connected by any affinity of materials, structures, Affinities or attractive forces hold together that are sufficient to hold the door handle assembly and the co-installed door together when subjected to a separation force below a desired threshold level for selective user door separation. As used herein, the term "field-coupled" means that opposing portions of the door handle assemblies mounted to each co-mounted door (i.e., the portion facing the door handle assembly) are coupled to each other and held together by an attractive field, which For example, between the magnets carried by each handle assembly part or between at least one magnet carried by one handle assembly part and at least one magnetic attraction structure carried by another handle assembly part (e.g., comprising one or more ferromagnetic The magnetic field established between the metal composite of the material). As used herein, the term "field-coupleable" means that opposing portions of the door handle assembly mounted to each commonly mounted door are configured to be field-coupled to each other. As used herein, the term "retain" or the phrase "secure the field-coupled handle assemblies together" and similar terms and phrases means that the interference coupling of the field-coupled door handle assemblies to each other is mechanically produced by the retaining assembly , so that when so mechanically coupled together one or both door handle assemblies and/or a Or the force required by the two doors themselves to separate the door handle assemblies (and thus the doors) from each other is greater than the separation force required to separate the door handle assemblies from each other when only connected or field coupled.

Referring now to FIGS. 1A-3B , there is shown a portion of a commonly mounted door arrangement 10 as an example of a swing door assembly, which includes two conventional doors 12 , 14 hingedly mounted to a door frame (not shown). In this regard, US Patent No. 10,808,438, incorporated herein by reference in its entirety, discloses a hinge assembly that allows co-mounted doors to swing together or apart in an inward pivoting direction. Specifically, the first inward door can be swung inward first, and then the second door can be swung inward, or both doors can be swung inward together. Figure 8A shows the co-mounted inner swinging doors with both doors pivoted inwardly about the hinge together to the open position of both doors. A hinge assembly provides such rotational movement. The mechanisms for selectively connecting and disconnecting the doors are discussed below.

As shown, a door handle assembly 15 is mounted on the door 12 and another door handle assembly 21 is mounted on the door 14 . As will be described in detail below with respect to FIGS. To withstand the force applied to the door to maintain the closed and locked door position.

Connect or disconnect the doors 12,14. It is contemplated, however, that the linkage elements 44, 54 may comprise elements other than magnets, which elements may at least similarly be used in connection with each other. E.g, Certain materials that are known to have a certain level of affinity for each other and thus can adhere to each other under certain conditions may be used as long as they release upon application of a desired threshold force. Structural interactions of elements positioned together may be used, including, for example, hook and loop mechanical fasteners or other microreplicated structures.

It is also contemplated that in some embodiments, no linkage elements need be used other than the retaining assembly structure described herein. The purpose of the linkage elements is to rotationally connect one handle set to the other so that they rotate together. As described below, each retaining assembly and its retaining components are provided to retain one handle set to the other as the doors move together. Although the linkage elements will compensate for the retaining assembly to prevent disengagement, they are not necessary for this purpose. Furthermore, linkage elements can be eliminated if rotational translation from one handle set to the other is provided by retaining structures or additional structures at the handle assembly interface. Such a structural part may facilitate a rotational connection for translation in one or two rotational directions.

The lock button 56 is configured to engage the interior recess 46A of the lock receiver 46 of the door handle assembly 15 when the door handle assemblies 15, 21 are coupled together (see, eg, FIGS. 4A-4C ), such that the just described door handle The locking operation of the assembly 21 is also performed in the door handle assembly 15 and vice versa.

The ring portion 50 is also preferably provided integrally or as a separate component for rotation with the magnet housing 52 . The loop portion 50 is further preferably operatively connected to a handle 55 . Although ring portion 50 and handle 55 are operatively connected to rotate together, handle 55 may be used to rotate magnet housing 52 and thereby open door 14 .

In the illustrated embodiment, the door 12 is, for example, a so-called "main" door, which serves as the main entrance door of the building. Inner surface 12C is the "inner" surface of door 12 because it is the surface of door 12 that faces the interior of the building, while outer surface 12A is the "outer" surface of door 12 because it is the surface of door 12 that faces the exterior of the building . Door 14 is for example an A so-called storm door mounted on a frame outside the door 12 so that the door 14 is exposed to the outdoor environment and the door 12 is located between the door 14 and the interior of the building. Inner surface 14A is the "inner" surface of door 14 because it is the surface of door 14 that faces the outer surface of door 12, and outer surface 14C is the "outer" surface of door 14 because it is the outer surface of door 14 that faces the exterior of the building. The surface of the building on which the doors 12, 14 are installed. It should be understood, however, that the just described door arrangement 10 is provided as an example only and that in alternative embodiments door 14 may be a main door and door 12 may be a storm door. In other alternative embodiments, the "storm" door 14 (or door 12) may instead be any other conventional door, examples of which include, but are not limited to, security doors, screen doors, secondary main doors, and the like. It will be further understood that although the drawings depict one example mounting configuration of the doors 12, 14 as viewed from the outside as in FIG. The concept is directly applicable to left-hand or right-hand side installation of doors 12, 14 and associated hardware.

The magnet assemblies 18, 24 of the door handle assemblies 15, 21 are mounted to the doors 12, 14 such that the magnets 44 carried by the magnet assemblies 18 are aligned with corresponding ones of the magnets 54 carried by the magnet assemblies 24 and are of opposite polarity to each other. . When the doors 12 , 14 are joined together, as shown in the example in FIG. 2 , the magnets 44 , 54 of opposite polarity are magnetically coupled to each other such that the magnet assemblies 18 , 24 and thus the doors 12 , 14 are field coupled to each other. If one of the handles 16A, 22A of the handle set 16, 22 is rotated in the direction to open the door 12, 14, this rotation is transmitted through the field coupling magnet assembly 18, 24 to rotate the other of the handles 16A, 22A, The two latch tongues 30 , 34 are thereby retracted into their respective latch plates 28 , 32 , as shown in the example in FIG. 2 . Therefore, if If the handle 16A is rotated in the direction to open the door 12, this rotation is transmitted through the shaft 48 to the cylindrical magnet housing 42 so that it rotates relative to the chassis 41. Because magnet 44 carried by magnet housing 42 is field coupled with magnet 54 carried by magnet housing 52 , rotation of magnet housing 42 causes magnet housing 52 to rotate in the same direction. Rotation of the magnet housing 52 in turn causes the camshaft coupled thereto to rotate in the door opening direction. This rotation of the camshafts of the door handle assemblies 15 , 21 in turn causes the respective latch tongues 30 , 34 to retract into their respective latch plates 28 , 32 . Rotation of the handle 22A in the direction to open the door 14 is also transmitted to the door handle assembly 15 to similarly retract the respective latch tongues 30, 34 into their respective latch plates 28, 32, thereby allowing the doors 12, 14 can be opened and closed together while being coupled together in the field. Furthermore, although field coupled together as shown in the example in FIG. 2 , the two door handle assemblies 15 , 21 can be actuated as described above by actuation of the lock button 17 and/or by a suitable key in the keyhole of the lock cylinder 23 . actuation together and simultaneously locks and unlocks.

In the illustrated embodiment, the door handle assembly 21 illustratively includes a mechanical stop that prevents it from turning in a direction opposite to the opening direction just described, or at least prevents the door handle assembly 21 from rotating in a direction opposite to the opening direction. Rotation in the opposite direction exceeds the selected rotation angle of the door handle assembly 21 . As the door handle assembly 15 is rotated in a direction opposite to the opening direction (see, e.g., FIG. 3A ) and the mechanical stop of the door handle assembly 21 is engaged, further rotation of the door handle assembly 15 in the same direction causes the surfaces of the field coupling magnets 44, 54 to move radially away from each other. At some point, through this rotation of the door handle assembly 15 to the point where the magnets 44, 54 are no longer field-coupled to each other and the magnet assemblies 18, 24 are disengaged from each other, an electrical gap is established between the magnets 44, 54 of opposite polarity. The magnetic field of is reduced so that the doors 12, 14 can be separated from each other, as shown in the examples in FIGS. 3A and 3B .

Further details relating to various embodiments of co-mounted door apparatus of the type shown in FIGS. The application is owned by the applicant of the present patent application, the disclosure of which is hereby incorporated by reference in its entirety.

As briefly described above, the door handle assemblies 15, 21 illustratively include a retaining assembly 58 for further securing the door handle assemblies 15, 21 together when coupled together as just described. Referring now to FIGS. 4A-5C , one embodiment of such a retaining assembly 58 is shown. Retention assembly 58 illustratively includes two parts, one part 60 mounted to magnet assembly 18 of door handle assembly 15 and the other part 70 mounted to magnet assembly 24 of door handle assembly 21 . As shown in Figures 4A and 4B (Figure 4A shows the magnet assembly 18 with a cover plate 47 mounted on the outwardly facing axial face of the cylindrical magnet housing 42, Figure 4B shows the cover removed The magnet assembly 18 of plate 47), the part 60 of retaining assembly 58 is exemplarily arranged in the form of retaining clip, and this retaining clip has: the closed end portion 64 that is fixed to the axial face of cylindrical magnet housing 42, from closed end respectively The portion 64 extends laterally and fits in the concave recess of the lock receiver 46 Upper retaining leg 62A, lower retaining leg 62B above 46A, and resilient legs 66A, 66B extending transversely from respective ones of retaining legs 62A, 62B. Retaining clip 60 is illustratively a spring structure with resilient legs 66A, 66B biased toward each other. A resilient leg retainer 68 is attached to the front surface of the magnet housing 42 on the opposite side of the lock receiver 46 to which the closed end 64 of the retaining clip 60 is secured. Block 68 defines a top surface 68A supporting elastic leg 66A and a bottom surface 68B opposite top surface 68A supporting elastic leg 66B. Resilient legs 66A, 66B are biased against top and bottom surfaces 68A, 68B of positioning block 68, which further operates to position retaining legs 62A, 62B over concave recess 46A of lock receiver 46 and receive relative to the lock. The concave recess 46A of the member 46 is positioned.

As further depicted in the example of FIG. 4C , part 70 of retaining assembly 58 is illustratively provided in the form of a frustoconical retaining ring having a smaller opening 72A and a larger opening 72B, the size of which is smaller. Designed to be received on the cylindrical shaft portion 56A of the lock button 56 , the larger opening 72B abuts the magnet housing 52 around the lock button 56 . Retention member 70 preferably extends radially outward from opening 72A to opening 72B in the shape of a tapered portion. A slot 74A is formed in and along the top surface of the retaining ring 70 , while another slot 74B is formed in and along the bottom surface of the retaining ring 70 opposite the slot 74A. The slots 74A, 74B are illustratively oriented to extend horizontally relative to the rest position of the magnet assembly 24 (i.e., the handle 22A of the handle set 22 is not rotated in either direction), and the retaining legs 62A, 62B of the retaining clip 60 are also oriented oppositely. Extends horizontally in the rest position of the magnet assembly 18 . The slots 74A, 74B are sized to receive axially therein a respective one of the retaining legs 62A, 62B.

The retaining legs 62A, 62B of the retaining clip 60 are illustratively positioned relative to the lock receiver 46 such that when the door handle assemblies 15, 21 are field coupled to each other as described above, the magnet assemblies 18, 24 contact each other and the retaining legs 62A are in the slots. 74A contacts retaining ring 70 below and retaining leg 62B contacts retaining ring 70 above slot 74B. When the lock button 56 is pushed into the recess 46A of the lock receiver 46, the retaining legs 62A, 62B move upwardly along the outer frustoconical surface 75 of the retaining ring 70 toward the corresponding grooves 74A, 74B. As the outer surface expands the distance between retaining legs 62A, 62B, it forces resilient legs 66A, 66B away from top and bottom surfaces 68A, 68B of positioning block 68 . As the retaining legs 62A, 62B are pushed higher on the frustoconical outer surface of the retaining ring 70, the retaining legs 62A, 62B eventually reach and are received in the slots 74A, 74B. As shown in the example of FIG. 5A , the biasing of the resilient legs 66A, 66B toward each other forces the retaining legs 62A, 62B into the slots 74A, 74B to secure the retaining clip 60 to the retaining ring 70 and thereby the magnet assembly 18. onto the magnet assembly 24. The interaction of retaining legs 62A, 62B within slots 74A, 74B thus creates a physical interference that retains magnet housing 42 to magnet housing 52 in the axial direction of shaft 48 . In some embodiments, the front edges or sides 74A1 , 74B1 of the slots 74A, 74B are formed at an acute angle with respect to vertical. In such an embodiment, the acute angle is exemplary chosen to normally maintain the retaining legs 62A, 62B within the slots 74A, 74B, but if a force greater than the threshold force acts on the door in a direction that separates the door handle assemblies 15, 21 On the handle assembly 15, 21, the retaining legs 62A, 62B are allowed to exit the slots 74A, 74B. Illustratively, in such embodiments, the threshold force is selected to be less than a force that would damage or destroy one or more components of the door handle assembly 15 , 21 .

In the illustrated embodiment, the retaining assembly 58 is configured to secure the field coupling magnet assemblies 18, 24 together as just described in their rest state (ie, as shown in FIGS. 2-3B , the handle 16A, 22A did not rotate in either direction). When either magnet housing 42, 52 is rotated relative to the respective chassis 41, 51 in a direction that causes the latch tongues 30, 34 to retract into the respective latch plates 28, 32 (i.e., when the doors 12, 34 are opened as shown in FIG. 14 o'clock), the magnet housings 18, 24 rotate together as described above, and as the retaining clip 60 and retaining ring 70 also rotate relative to the corresponding chassis 41, 51, the retaining legs 62A, 62B are maintained in the slots 74A, 74B, as An example is shown in Figure 5B. Conversely, when the magnet housing 42 rotates in the opposite direction and the magnet housing 52 is prevented from rotating therewith by the mechanical stop of the door handle assembly 21, the retaining clip 60 rotates relative to the retaining ring 70, the diameter of the retaining clip 60 relative to the retaining ring 70 The forward movement causes the retaining legs 62A, 62B to radially exit the slots 74A, 74B onto the conical surface 75 of the retaining ring 70, as shown for example in FIG. 5C. This forces the resilient legs 66A, 66B further away from the top and bottom surfaces 68A, 68B of the positioning block 68, as shown for example in FIG. 5C. While the inward bias of the release spring legs 66A, 66B forces the spring legs 66A, 66B toward each other, the inward bias of the spring legs 66A, 66B toward each other forces the retaining legs 62A, 62B along the axis of the conical surface 75 of the retaining ring 70. Moving away from the slots 74A, 74B and toward the opening 72A separates the retaining legs 62A, 62B, thereby separating the retaining clip 60 from the retaining ring 70 . Eventually, resilient legs 66A, 66B contact top and bottom surfaces 68A, 68B of positioning block 68, which repositions retaining legs 62A, 62B to their pre-contact positions shown in FIGS. 4A and 4B.

The following description refers to safety installation or involving any interior swing door. The safety devices described below are intended to increase the strength and safety of a closed inner swing door in the direction of rotation opposite to the direction of rotation of the inner swing, ie the direction of outward swing. In particular, the structural features of the new creation are designed to withstand the force in the outward swing direction of the door, so as to prevent the inner swing door from being severely damaged or invalidated due to the application of force in the outward swing direction. This outward force can be applied as a push force from the inside of the swinging door, or as a pull force from the outside of the door. It is expected that the swing door of the present invention will be able to withstand an outward force greater than fifteen hundred pounds, more preferably greater than two thousand pounds.

For example, with a single swing door, the push force may come from an accidental or accidental bump to the inside of the door, or from a deliberate push to lock the door. When the door is locked, a pulling force can be applied from the outside where the lock and door need to remain locked and withstand the force applied. For co-mounted door assemblies, this thrust from the inside of the door can be selectively applied to either door, such as when both doors are closed, or when the inner door is open and the outer door ( such as storm doors) are closed and locked. Likewise, a pulling force can be applied to the outer door when the inner door is closed or opened. It is also contemplated that when the two doors are closed from within the space between the two doors by any passage through either door or another part of the door assembly, thrust can be applied from the space between the two doors to the co-mounted door The outer door of the component. It is an object of the present novel creation to improve the security of an interior swing door in any of the above or proposed arrangements to withstand forces in the outward swing direction and to maintain the structural integrity and operability of the door when subjected to such forces. When such a swinging door is locked, another purpose is to maintain the door locked when subjected to such forces.

Figures 6A to 20 illustrate the incorporation of certain security devices into the co-mounted door assembly described above. Specifically, these safety devices are shown and described as providing external Interior swing door 14, if interior swing door 12 is not provided, these safety features would be another example of some of the safety features provided to single leaf interior swing doors. The safety device of the present invention increases the ability of the door to withstand forces that may be applied to close the door when it is in the closed position. For swinging doors, the purpose is to withstand the outward force against the door when in the closed position. The following safety devices are described as being suitable for swinging doors, as this is the case for commonly installed doors. It will be appreciated that each of the features discussed below can also be used in the opposite direction of the features and components to increase the safety of the outward swinging door when it is subjected to inward forces in the closed position.

Referring to FIG. 6A , the inner swing door 12 is shown positioned in a coupled position with the outer swing door 14 . FIG. 6A is a schematic cross-sectional view in a horizontal plane passing through the center of the door handle assembly 15 , 21 . In particular, magnet housing 42 of door handle assembly 15 of door 12 is shown partially nested within magnet housing 52 of door handle assembly 21 of door 14 . In this position, the magnets as described above may be attractively aligned such that the inner door 12 is magnetically coupled with the outer door 14 .

When either handle set 16 or 22 is turned, the latch tongues 30, 34 of the inner door 12 and outer door 14, respectively, can be retracted, and the doors 12, 14 are coupled to swing inwardly. As shown, the latch tongue 30 in the rest position is positioned within a cavity 80 of a door frame 81 which preferably includes a strike plate 83 (see also FIG. 8B ) for added integrity. The stationary latch tongue 34 is similarly positioned within the cavity 82 of the door frame 81 . As shown, to increase the integrity of the cavity 82 , an impingement plate 84 is preferably disposed around the cavity 82 .

Also shown is structural rail member 86 secured against frame 81 to be rigidly secured to frame 81 and to provide a latch side stop surface 88 whose purpose is to provide Outer limiting elements to limit the range of door closure. Flexible weather stripping 90 preferably extends from the channel and latch side stop surfaces of structural rail member 86 toward the exterior door surface for engagement therewith in the closed exterior door position. A flexible weather strip 92 is also preferably attached to the door frame 81 so as to extend to contact the surface of the inner door in the closed position. The weather stripping 90, 92 itself is known to be made of many different materials to be flexible, resilient, and form a seal with the door surface. The resilient nature of the weather stripping 90, 92 tends to move the portion of the door exterior surface near the latch side stop surface 88 slightly away from the latch side stop surface 88 and positions both latch tongues 30, 34, respectively, as desired. Within cavities 80,82.

FIG. 6B shows the enlarged area of FIG. 6A with the outer door 14 in the closed position with the latch tongue 34 extending within the central portion of the cavity 82 and extending unobstructed through the opening of the strike plate 84 . In this position, rotation of either handle set 16 or 22 can cause the latch tongues 30, 34 to retract.

Also shown is the latch tongue 34 having a notch 94 which may preferably be provided along the axial extent of a portion of the latch tongue 34 extending from the side edge of the door 14 where the latch assembly 26 is in a stationary or non-static position. Reverse position. Furthermore, the notch 94 is preferably open toward the edge of the opening defined in the strike plate 84 in the direction in which the outer door 14 is closed. 8A and 8B show the cavities 80 , 82 and the positions of the strike plates 83 , 84 mounted to the door frame 81 . The striker plate 83 includes an opening 95 and the striker plate 84 includes an opening 96 . The strike plate 83 is shown secured to the door frame 81 for rigidity. As shown, an edge 97 of the strike plate 84 defining the opening 96 and facing the notch 94 of the latch tongue 34 preferably includes a tab 98 extending within the opening 96 away from the edge 97 . Tab 98 is preferably sized and shaped to fit within recess 94 . As shown in Figures 7A and 7B, the size of the notch 94 The sum shape is preferably determined by a notch bottom 99 and side portions that define a notch 94 within the volume of the latch tongue 34 .

The above arrangement, including notches 94 and tabs 98, may provide a safety device according to the present invention when an outward force is applied to the outer door 14, either directly or indirectly through the inner door 12. FIG. 6C illustrates the interaction between notches 94 and tabs 98 when such an outward force is applied. Although upon further closing movement of the outer door 14, the tab 98 is aligned to fit within the notch 94, such further movement will cause the relative displacement of the tab 98 from the non-blocking position (allowing the latch tongue 34 to freely retract). to a blocking position at least partially within the depth of notch 94 . Movement of the latch tongue 34 with the door 14 under external force causes the tab 98 to displace within the notch 94 . At least partially capturing the tab 98 within the notch 94 will not only prevent the latch tongue 34 from retracting, such engagement may also prevent further movement of the door 14 relative to the frame 81 . The positive stop can also be formed by engaging the tab edge 100 of the tab 98 with the notch bottom 99 , although it is not necessary for the tab edge 100 and the tab 98 to engage to prevent further movement of the door 14 relative to the frame 81 . It should be noted that limited movement of the door 14 in the closing direction may be facilitated at least in part by the folding of the weatherstrip 90 . As also shown in FIG. 6C, a portion of the door side surface may engage the latch side stop surface 88 at approximately the same point where the tab edge 100 engages the notch bottom 99, thereby providing greater resistance to the structure. ability of external forces.

A similar effect for preventing retraction of the latch tongue 34 and limiting movement of the door 14 relative to the door frame 81 may be provided by an outward protrusion positioned along the surface of the latch tongue 34 rather than a notch 94 . The protrusion can be positioned in a similar position as the notch 94 shown, and can provide a similar surface, such as that provided by the most pointed inward surface of the notch 94. provided. Such a protrusion will capture the tab 98 with any slight movement under the outward force of the door 14, as shown in FIG. space thereby preventing retraction of the latch tongue 34. The protrusion will extend sufficiently to engage the door 14 under such outward force, but extend and retract uninterrupted during normal extension and retraction of the latch tongue 34 under normal operating conditions.

9A-10B illustrate another embodiment of a safety device provided to the outer door 14 to improve the ability of the door 14 to withstand outward forces and prevent movement of the door 14 relative to the door frame 81 . Instead of the notches 94 engaging the tabs 98 of the strike plate 84 as described above, the notches 94 of the latch tongue 34 will engage the tabs 198 when moved in the door closing direction (eg, by an applied outward force). Engaged, the tab 198 may be formed as an extension of the structural rail member 186 . FIG. 9C shows the notch 94 moved slightly in the direction of the arrow so that the tab 198 is located within the notch 94 .

The tab 198 may be formed as an integral part of the structural rail member 186 secured to the door frame 81 for rigidity. Structural rail member 186 may comprise an extrusion of metal, such as aluminum or steel, with tabs 198 machined to extend from edges of the extrusion. Tabs 198 may be formed using other conventional metal fabrication techniques, including integral with metal extrusions, such as by welding. In any event, the tab 198 extends over a side edge portion of the cavity 82 of the door frame 81 , functioning in a manner similar to the tab 98 of the strike plate 84 described above.

FIGS. 11A to 12B illustrate additional safety features provided to the outer door 14 to improve the ability of the door 14 to withstand outward forces and prevent movement of the door 14 relative to the door frame 81. an example. This embodiment is similar to the embodiment of FIGS. 9A-10B described immediately above, except that the tab 298 is provided as a separate element relative to the door frame 81 . Tabs 298 are provided to extend over side edge portions of cavity 82 , functioning in a manner similar to tabs 198 of structural rail member 186 or tabs 98 of strike plate 84 as described above.

As shown in FIG. 11A , structural rail member 286 may be similar to structural rail member 86 of FIG. 6A without the extension forming tab 198 of FIG. 9A . Tab 298 may be rigidly secured to door frame 81 in a number of ways. For example, one end of the tab 298 may be inserted into a recess of the door frame 81 disposed within the cavity 82 . The tab 298 may have other structural features that may be used to secure the tab 298 within the cavity 82, such as by screws or other fasteners. Tab 298 may be glued in place. As shown in FIG. 12B , tab 298 may fit behind a portion of structural rail member 286 . In any event, the tab 298 extends inside the side edge portion of the cavity 82 of the door frame 81 , functioning in a manner similar to the tab 98 of the strike plate 84 described above and similar to the tab 198 of the structural rail member 186 described above.

It is contemplated that any means may be used to create the tab operatively connected directly or indirectly to the door frame. Such tabs in the embodiments described above should be positioned so that at least a portion of the tab engages at least a portion of the notch 94 to limit further movement of the door relative to the door frame 81 upon further movement of the closing door subject to force in the closing direction. .

13A-15B illustrate yet another embodiment of a safety device provided to the outer door 14 to improve the ability of the door 14 to withstand outward forces and prevent movement of the door 14 relative to the door frame 81 . In this embodiment, a latch tongue 334 without a notch can be used, as 14B, with strike plate 384 that does not include tabs, such as tabs 98, as shown in FIG. 15B. Instead of the latch tongue notch and tab engagement as in the previous embodiments, the outward force may be absorbed by a safety device arranged to act between the outer surface 14C of the door 14 and the structural rail member 386 .

In particular, the outer surface 14C of the door 14 may be provided with a rib 399 extending at least partially along the side edge of the door 14 but spaced slightly inwardly from the side edge. The rib 399 may be formed as an integral part of the door 14, or may be integrated along the outer surface of the door by other conventional techniques. The structural rail member 386 preferably includes a channel 387 that may be formed as an extrusion with the remainder of the structural rail member 386 by a flange portion 398 extending at least partially along the structural rail member 386 . Channel 387 is preferably positioned to open toward the outer surface of door 14 and more specifically accommodates rib 399 . As shown in FIG. 13B , rib 399 may extend partially within channel 387 when door 14 is closed and at rest. When an outward force is applied to the door 14, the rib 399 will move further within the channel 387 and may also move slightly away from the door frame 81 as indicated by the arrow. This slight movement away from the door frame 81 will occur because the door 14 actually pivots around its hinges when this outward force is applied, which is exaggerated in FIG. Arrow of the vector component of the move). As shown in FIG. 13C , the engagement of rib 399 and flange portion 398 along the sides may secure door 14 to door frame 81 via structural rail member 386 rigidly secured to door frame 81 .

16A-17B illustrate yet another embodiment of a safety device provided to the outer door 14 to improve the ability of the door 14 to withstand outward forces and prevent movement of the door 14 relative to the door frame 81 . This embodiment is similar to the implementation of FIGS. 13A-15B described immediately above. An embodiment has a safety device arranged to act between the outer surface 14C of the door 14 and the structural rail member 486 .

Instead of forming a rib extending at least partially along the outer surface 14C of the door 14, the plate 497 may be conventionally secured to a portion of the outer surface 14C of the door 14, such as around the handle set 22, as shown in FIG. 17B. It is contemplated that a separately provided element such as plate 497 may extend only partially along the side edge of door 14, and that plate 497 may be rigidly secured to door 14. As shown, the plate 497 may be provided with a rib 499 extending at least partially along an edge of the plate 497 .

Plate 497 is spaced slightly from the side edges of door 14 so as to be at least partially received by channel 487, which may be formed with structural rail member 486 rigidly secured to door frame 81 as described above. Channel 487 may extend along the entire length of structural rail member 486, such as if formed as an extrusion, but is not required. Plate 497 may be positioned anywhere along the door side edge as long as it is positioned such that rib 399 can be received by channel 487 . It should also be noted that multiple such panels similarly positioned along the edge of the door could be used. In any event, the rib 499 is engageable with the flange portion 498 upon application of a force outwardly as indicated by the arrow in FIG. 16C from the position shown in FIG. 16B . As noted above, this movement may include a slight movement of the door 14 away from the door frame 81 as part of the rotational movement. Such action will prevent the door 14 from moving relative to the door frame 81 for added security.
